Answer:
MgCl2
Explanation:
From the question given,
Mass of Mg = 3.6g
Mass of the chloride = 14.25g
Note: the chloride contains Mg and Cl
Mass of Cl = Mass of chloride — Mass of Mg
Mass of Cl = 14.25 — 3.6 = 10.65g
Now we can easily obtain the formula of chloride as follow:
Mg = 3.6g
Cl = 10.65g
Divide by their molar mass
Mg = 3.6/24 = 0.15
Cl = 10.65/35.5 = 0.3
Divide by the smallest
Mg = 0.15/0.15 = 1
Cl = 0.3/0.15 = 2
Therefore, the formula of chloride is MgCl2

Answer:
Explanation:
Here, a balance between attraction between nucleus and electrons, and electron-electron, and nuclei-nuclei repulsion play role.
All chemical bonds are formed by overlapping of orbitals. If the electronegativity of the two elements forming the bond is very different (elements from the 1st ,2nd groups with elements of 7th group) then ionic bond are formed. If the electronegativities are more similar, then overlapping is stronger, and covalent bonds are formed.
Answer:
you can identify an unknown substance by measuring its density and comparing your results to a list of known densities. Density=mass/volume. Assume that you have to identify an unknown metal. You can determine the mass of the metal on a scale.
